Full movie description "Swooner Crooner":

Hens are working in the "Flockheed Eggcraft Factory", laying eggs for the war effort until they get distracted by a rooster singing like Frank Sinatra. Porky, the supervisor, rushes to investigate. Soon, he's auditioning for a new crooner; among those showing up are caricatures of Al Jolson, 'Jimmy Durante' and Cab Calloway. He evetually gets to a Bing Crosby clone, who introduces himself as "The Old Groaner". Between the two of them, egg production is soon more than he can handle.

Reviews of the Swooner Crooner

In the only Porky Pig cartoon to receive an Oscar nomination, filmdom's most famous swine owns a farm and has the hens lay eggs all day - to the tune of (what else?) Raymond Scott's "Powerhouse" - but the hens get distracted by a crooning rooster. But when Porky hires another rooster to woo the hens back, the whole ordeal really turns into a battle of wits.

An obvious aspect of "Swooner Crooner" is that it's truly a product of WWII, what with the clear allusion to Rosie the Riveter. But of course, they parody singers like Bing Crosby and Frank Sinatra. Yeah, those guys may have been really popular in those days, but I just bet that most people in my generation believe that BC and FS deserved to get mocked as brutally as possible.

OK, so I don't know whether or not I can speak for every member of my generation. But I can say that this is a really funny cartoon. It got included in Leonard Maltin's "Bugs and Daffy: Wartime Cartoons".
